Dual 5700 Kv Mamba Maxx

[ssspconcepts]

Well I received my dual flightpower 3S 5000mah lipos (to be wired in parallel to dual mambas 5700kv in parallel) and new MRC 989 charger. Getting closer to finding out what dual bl can do. Hopefully I will have some result to report this weekend. BTW, here are some pics of my new paint...FranksBodies did the paint....I can't take credit for his art.

Looks great SSS! Let us know know how it runs as soon as you can. Are you going to swap tires for your speed runs? Those puppy's look like they will baloon pretty good.

I've been testing a Mamba Maxx with 5700BL motor with 3S lipo the MM esc gets too hot and shut down after about 5 mins Temps get around 125F. Is the setup under sized for a Emaxx or would a cooling fan on the MM esc help from shutting down? Motor runs cooler about 85F but I have a cooling fan with heat sink on it. Also I use the Ubec from the MM would it better to have a seperate Ubec?

That set up is WAY to small for an e-maxx. The ESC would work, but I am not surprised the motor is getting so hot. It is designed for a light 1/10 scale 2wd buggy or truck.'

Getting an external BEC will definitely help.

pics don't work for me, I wanna see!

Hey all,

Thanks for your continued interest and for keeping this thread alive.

I have been really busy with a new assignment at work and my time on the forum and with RC Monster Trucks has been limited. I essentially built two very similar trucks...one with a 4.5 Novak (with combo bulks & 1/10 hardened gears) and the other a Dual 5700kv Mamba (with hybrid bulks & 1/8 hardened gears).

About two weeks ago I took the Novak truck out for one serious bashing session in order to push it to its limit...the 1/10 diffs failed. Since then I have done an extensive rebuild and have replaced the diffs with UE spider 8 gears. I also replaced the two-speed tranny for a G-Maxx single speed tranny with metal gears. I have also ordered a Neu Motor and will be replacing the Novak 4.5 system with a Neu/Quark 125 combo...all to be powered by 5S lipo.

I want to compare the two trucks and see which performs better. It won't be long now.

Sombody asked price...yikes! I HAVEN'T KEPT TRACK, BUT I'D SAY IT IS SAFE TO SAY THAT EACH TRUCK IS WELL OVER $2k (not including radio gear).

BTW. Somebody asked if the dual Mamba system gets hot....yes it does. However it doesn't get any hotter than my single 5700kv Mamba powered 1/10 stadium truck used to on 3S.

The dual system runs dual 5700KV Mambas in parallel and dual 3S FP lipos in parallel. Power and speed is incredible.
